Windows 10 Password lost

Hello There!

I am at my friend's house - he installed windows 10 the other day. Now when he boots up, there is a different user name appearing - somebody who used to live here and he does NOT know her password. He would just like the default user & the ability to get in. How can I crack into Win10 & recover for him. Windows 10 is ONLY Booting to the other person's profile & cannot get in at all.

Thank you for any help you can provide. This is a very strange problem because he has no recollection of ever making this person a user on his PC. But somewhere along the line he must have and he has totally forgotten. He is 75 years old & needs to get onto his PC. Thank You

Years ago I was an MSP & certified in Cisco also but I do NOT know how to get into Win 10. Tried to use a repair & image disk of Win 7 - but I stopped because I do not want to trash his data.

Any effort to help me solve this would be appreciated.

You'll probably need to enable the hidden Administrator account in order to get your user / password problems sorted out.

You'll need to boot from the installation media. If you do not have the installation media on hand you can download the ISO from here
Once you have the ISO, you can use ImgBurn to burn it to a DVD or Rufus to burn it to a USB ThumbDrive, either of which you can use to boot your computer.
Follow the steps outlined here

Another option that I have used successfully is a third party software boot disk.

NOTE.... IF the computer is UEFI with "Secure boot" enabled, I don't believe you will be able to boot from the CD you create from the ISO (Offline Windows Password & Registry Editor, Bootdisk / CD, the pogostick link immediately above) unless you enter the System Setup Utility (BIOS) and turn off Secure Boot and change the boot option from UEFI to Legacy or UEFI + Legacy or UEFI + MBR depending on what's avaialble and how robust your BIOS might be (if it even supports changing turning off secure boot, some newer ones do not.
